10 Claims.

This invention relates' toenameled metal wall corner construction and to a method for its assembly.

v. In'my copending application entitle-d Enam- 5 eldmetalwallconstruction, Serial No. 742,029,

iledfA'u'gust` 30,' 1934; there is disclosed a construction' wherein the enameled'metal plates are pr'eabricatedon insulation board backingv so as t'o" provide individual panels of metal veneered lO` boa'r-dthat can bereadily assembledin the construction of'. internal' orY external walls; Since thereis n'o interlocking of the panels with each Otlier'jra'ny panel can be' quickly and" easily removedfrom the facesi-de without disturbing any l5' of the adjacent panels;

The' metal panels, whichusually become warped at' the high temperatures employed for burning on the'enamel; are* cemented under high pressure "to rigidinsulatingfboards, both for the pur- 20 posent pressing the enameled metal to straighten it' out` andalso to'eliminate the tendency of the nietalltobuckleunder climatic conditions. Furthermore, the. heavy insulating boards notV only prevent` sweating' of the metal but" also act as sound'r deadener' and heat insulation. In wall construction; thesepanels are supported in spaced relationand" the resultingjoints are allcaulked, sothat no metal-touches'V metal andthe edges of Y, the panel are protected by'a' waterproof caulking 3'0 compound; Ail oftlie'e'dges `oi ythe enameled metal panelsY are, at the-same time, protectedv against rusting byl the caulk'ingv compound.

Myj present invention relates toV the use of this type ofmetal'vene'ered panel in inside and outside` corner constructions and contemplates the provision4 offnovel'means for the assembly of the'met'al: veneered" panels to` present corners ofwater tight construction and ofpleasing appearance.

It is therefore an object of this invention to provide'4 an` enameled metal wall corner construction of" a novel 'andl improved type wherein tlejoints formed areiwater tight and; present a pleasingH and artistic appearance.

It; isa further' important objectv of this invention to provide'a wallv corner constructionusing metal'veneeredpanelswhereby both internal and external corners can be constructed in a'simple and efli'cient" manner.

t OtherA andl further important objects of this invention will'beapparentl from thedisclosures in the specification and the accompanying drawing.

invention (in a preferredV form) is illustrated inthe drawing and hereinafter more fully 55 described;

(Cl. 18S- 85) On the drawing:

Figure 1 is a broken horizontal sectional view of a corner construction embodying the principles of my invention.

Figure 2 is an enlarged fragmentary sectional View of the inside corner construction-shown in Fig. 1.

Figure 3 is an enlarged fragmentary sectional view of the outside corner construction shownin Fig. 1.

Figure 4 is a sectional view taken substantially on the line IV-IV of Fig. 3` with parts in elevation.

As shown on the drawing:

The reference numerals I and I I indicate generally outside walls and the reference numerals I2 and I3 inside walls of enameled metalpanel construction embodying the principlesof my invention. Each ofv said walls I0 and IIis built' up of a plurality of panels I4 comprisng'a backingof rigid insulation board I5 .and a veneer of'porcelain enameled metal I6 secured thereto by means of a layer of Aadhesive Ill. Said panels I4 are prefabricated by uniting the metal'veneer I64 to the insulation board backing I5 un-der high pressure to cause a firm bond therebetween and prevent warping of the metal veneer under changes in climatic conditions.

In the construction of an external corner, a corner member I8 is used comprisingv awood strip having V-shaped rectangular grooves arranged in opposed pairs Iii-I9 and 20-20 along opposite sides thereof. The outside pair oi" grooves Iii-I9 are adapted to receive the adjacent end edges of the insulation board I5'of the panels I4, the joints thereby formed'being rendere-d water tight by the use of a caulking material 2i. Said grooves I9-I9 are of such size as to snugly receive the end edges of said insulation board backing I5 and permit the extended edges 22 of the metal veneer to overlie the corresponding faces 23 of the corner member I8.

An angularly formed sheet metal retaining strip 24 (Fig. 3) is secured over the external corner by means of screws 25 or other suitable fastening means, so as to overlie the extended marginal portions 22 of the metal veneer panels. Said-strip 24 is provided with reversely turnedlateral edges 26 which lare adapted, by virtue of the resiliency of the sheet metal, to press against the external faces of said marginal portions 22 and form a tight seal therewith. The space thus formed between the corner member I8 andthe retaining strip 2llis filled with a caulking compound 21.

An external cover trim 28 is adapted to be snapped in place over the retaining strip 24 and for this purpose is provided with reversely turned anged edges 29 that engage over the rounded lateral edges 2B of the retaining strip. Said retaining strip and cover trim extend substantially the full height of the corner members i8 but at the top and bottom thereof are supplemented by other sheet metal members that serve as plinths. One of such plinths, indicated by the reference numeral 33, is shown in Fig. 4 and comprises a member formed of stamped sheet metal to provide a lower horizontal flange 3l adapted to be secured to the bottom of the vertical corner member I8 by screws 33 or other suitable fastening means. The plinth 33 extends out beyond the corner edge of said member I8 toI provide a space that is filled with the caulking material 2. The projecting portion 34 of the plinth 30 is joined by a beveled portion 35 to an extension 3G that lies in back of the cover trim 28 and ilush with the retaining strip El! in abutting relation therewith. Screws 31 secure the plinth in place through the extension 36.

Horizontally extending stringers 38 lie in back of the panels H at spaced intervals to pro-vide suitable supporting structures for the panels. Said stringers 38 are secured at their ends in the opposed pair of rectangular notches or grooves 2?.

The inner corner construction includes a vertically extending wooden corner member i0 connected to the outside corner member I8 by means of suitable braces lil. Said corner member 60 is provided along its inner face, which extends diagonally across the corner, with a plurality of pairs of grooves ll-4l and 42-42 for receiving the end edges of the panels making up the inside walls l2 and I3, and the end edges of the inside sets of stringers i3-43, respectively. Other braces 44 and 45 extend between the stringers 43 and 33 to form a rigid wall construction.

As in the outside wall construction, the joints are caulked and retaining strips and cover trim are employed to conceal the corner and overlie the extended marginal portions of the metal veneered panels. In the inside corner construction, the retaining strip 46 is secured by means of screws 41 (Fig. 2) to the corner member 4E! and a cover strip 48 is fastened over the retaining strip. Said retaining strip 46 is provided for this purpose with rounded lateral edges 49 over which similarly rounded edges i) of the cover strip 38 are adapted to be snapped and resiliently retained in place. An inside sheet metal plinth 5| is provided for the inside corner at the base thereof.

I am aware that many changes may be made and numerous details of construction may be varied through a wide range without departing from the principles of this invention, and I, therefore, do not purpose limiting the patent granted hereon otherwise than necessitated by the prior art.
